Amazon Basics usually states an overall dimension including wheels in its About this Item bullet, and a second, differently labeled figure in the Product Details Item Dimensions table; on several listings that table figure is smaller and is the case body only, confirmed most clearly on the 15 inch softside carry-on where the bullet explicitly reads 15(H) inches excluding wheels against an 18.1 inch table height. On other listings, such as the 26 inch and 30 inch hardside checked models, the bullet and table give the same including wheels number with no separate body only figure published anywhere on the page, so bodyOnly is null for those. Amazon also does not use a consistent physical meaning for L versus W versus H from listing to listing, so the three numbers should be read as a set rather than a strict length or width or height mapping.
